Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of precast reinforced concrete slabs, in particular to a reinforced concrete structure with strong bearing capacity. Background Technique
[0002] Reinforced concrete structure is a common type of building and engineering structure. It combines the advantages of two materials, steel bars and concrete, to form a composite material structure that is both strong and has good plasticity and durability. It is a brittle material composed of cement, sand, gravel and water mixed in a certain proportion. During the hardening process, cement reacts chemically with water to form a strong cement stone, which firmly cements sand and gravel together.
[0003] In the actual construction process, reinforced concrete structures are mainly used for weight bearing, and the quality of their bearing capacity is directly related to the bearing capacity. Therefore, designing a reinforced concrete structure that can support with high strength can greatly improve the quality of reinforced concrete structures. And the common one-piece casting requires on-site casting and a long waiting time for solidification, resulting in a long overall construction period. While precast reinforced concrete structures can well solve such problems, but it is difficult to precast large reinforced concrete slabs and transport them, and they cannot be adjusted according to actual required sizes. Therefore, it is necessary to design a strengthened combined precast reinforced concrete structure. Content of the Utility Model

[0006] Preferably, the connecting sleeves are equally spaced in groups of two. An injection pipe is fixed at the upper end of the upper connecting sleeve. A connecting pipe is fixed between each group of connecting sleeves. The upper end of the injection pipe is aligned with the upper end of the concrete layer.
[0007] Preferably, the bottom metal support layer is composed of a bottom metal plate and a corrugated plate. The corrugated plate is arranged above the bottom metal plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] Please refer to Figures 1-4, the utility model provides a technical solution: including a main board 1 and a connecting board 2. Bottom metal support layers 4 are provided at the bottoms of both the main board 1 and the connecting board 2. A concrete layer 3 is provided above the bottom metal support layer 4. A reinforcing layer 6 is provided at the central position within the concrete layer 3. Carbon fiber cloth 5 is embedded on the surface of the concrete layer 3. Connecting sleeves 11 are embedded on both sides of the main board 1. Threaded columns 21 are fixed on both sides of the connecting board 2. The ends of the threaded columns 21 are inserted into the corresponding connecting sleeves 11. The reinforcing layer 6 includes threaded steel bars 61 and ring-shaped steel bars 62. The threaded steel bars 61 pass through the concrete layer 3 and are evenly distributed within the concrete layer 3. The ring-shaped steel bars 62 are arranged in a rectangular structure, and the four corners are sleeved around the peripheries of four adjacent threaded steel bars 61.
[0019] The bottom metal support layer 4 is composed of a bottom metal plate 41 and a corrugated plate 42. The corrugated plate 42 is arranged above the bottom metal plate 41. Locking bolts 43 are evenly arranged between the corrugated plate 42 and the bottom metal plate 41. The upper ends of the locking bolts 43 pass through the bottom metal plate 41 and the corrugated plate 42 and are threadedly connected with fixing nuts 44. A lifting ring 7 is fixed at the upper end of the main board 1. The bottom of the lifting ring 7 is inserted into the concrete layer 3 and is fixed to the threaded steel bar 61 within the reinforcing layer 6.
[0020] The connecting sleeves 11 are equally spaced in groups of two. An injection pipe 12 is fixed at the upper end of the upper connecting sleeve 11. A connecting pipe 13 is fixed between each group of connecting sleeves 11. The upper end of the injection pipe 12 is aligned with the upper end of the concrete layer 3.
[0021] Working principle: First, pass the locking bolts 43 at the upper end of the bottom metal support layer 4 through the bottom metal plate 41 and the corrugated plate 42, and fix them at their ends with fixing nuts 44, thereby fixing the bottom metal plate 41 and the corrugated plate 42. Then place them at the bottom of the precast mold. After knitting and fixing the threaded steel bars 61 and the ring-shaped steel bars 62 of the reinforcing layer 6, place them above the bottom metal support layer 4. At the same time, fix the lifting ring 7 at the upper end of the threaded steel bar 61. Then conduct concrete pouring. At this time, the connecting sleeves 11 can be embedded at the specified positions on both sides of the concrete layer 3. Finally, lay the carbon fiber cloth 5 above the concrete layer 3. After solidification, a complete main board 1 is formed. The entire bottom of the main board 1 is supported by the bottom metal support layer 4, making the stress at the bottom of the concrete layer 3 more uniform. At the same time, the carbon fiber cloth 5 can reduce the stress concentration within the concrete layer 3, ultimately achieving the purpose of enhancing the support capacity. When connecting the main board 1 and the connecting board 2, the threaded columns 21 on both sides of the connecting board 2 can be inserted into the corresponding connecting sleeves 11. Then, through the injection pipe 12, inject concrete into the connecting sleeves 11 to completely fill the connecting sleeves 11. After solidification, the threaded columns 21 are fixed within the connecting sleeves 11, completing the combination purpose. The operation is simple, it can be quickly assembled on-site according to the actual laying area, and it is convenient for transportation.
